Shafts 93 carrying beveled cog wheels 92 which mesh with the beveled cog wheels 48are provided tojprovi de means for dynamos and other apparatus. A

onorete pier 94 carrying an anchor colunign 95 s located a considerable dlstance from the abutments 1 in the upper stream in: linewith the Center of the fin wheel 82. A raft 96,

by one end 97 is, sli'din'gly secured to the anchor colu'rnri 95 while its opposite end 97 carries a rod 98. A wire netting or screen 99 is secured to the rods 98 and 21 to preventlog'sland other re'f use cornin g downstream from ologging or breaking the fin wheel 32.

In Figure 19 is shown an arrangement of two fin wheels 32 being mounted on the hoisting bases 4. "In this arrangement four square shafts 39 and two right hand worm hoisting screws 50 and two left hand worm hoisting screws 51 are used. Each square shaft 39 operatively communicates with a.

worm hoisting screw through the medium of a hoisting gear shift block 68. The arrangement (IlGSCllbQ-Cl, as shown. 1n Figure 19 is preferred, and gives best results in rivers 25 feet or more in depth.

The device when located in a deep current river as described will operate as follows: The currents of water passing through the netting or screen 99 bear upon the submerged. plates 34 of the fin wheel 32 and rotate the same, thus causing the shaft 30 to which the said fin wheel 32 is rigidly secured to rotate the square shafts 39, which supply the shafts 93 with power through the beveled cog wheels 48 and 92, through the medium of the beveled cog wheels 31 and 40. The fiat boats 11 upon which the hoisting bases 24 rest are always submerged a certain distance and raise or lower with the rise or fall of the river. WVhen the river falls and the flat boats 11 lower with the fall of the river, the hoisting bases 24 which carry the fin wheel 32 thru the medium of the shaft 30, are suspended upon the worm hoisting screws 51. In order that they may be readily lowered so that the plates 34 of the fin wheel 32 may be submerged to their normal depth, the hoisting gear, shifting blocks 68 are shifted, until the beveled gears 79 mesh with the beveled gears 46 and 57, which cause the said worm hoisting screws 51 to rotate, due to the rotation of the square shafts 39 and thus lower the hoisting bases 24. When the river rises, in order that the flat boats 11 may raise and the fin wheel 32 be raised to its normal depth, the hoisting gear shifting blocks 68 are shifted until the beveled gears 80 and 81 mesh with the respective beveled gears 46 and 57 so that the worm hoisting screws 51 may rotate and thus raise the hoisting bases 24 so as to permit the said flat boats 11 to raise. If it is desired to sink the flat boats 11 in order to submerge the fin wheel 32 below its normal depth, the valves 15 of the flat boats 11 are opened and water permitted to enter the compartments 14 until the said flat boats 11 are submerged to the desired depth, whereupon the hoisting gear shifting blocks 68 are shifted until the respective gears come in mesh in order to lower the hoisting bases 24 through the medium of the worm hoisting screws 51. When it is desired to raise the fiat boats 11 the valves 15 and 16 are opened; the valves 15 being opened to permit the expulsion of the water from the compartments 14, while the valves 16 are be supplied by compressors (not shown) mounted upon the hoisting bridges 4 and driven indirectlyby the fin wheel 32 into the j compartments 14 for raising the said flat boats 11'. 1 J v lVhile I have herein described a certain specific method of constructing and assembling the elements of my invention, it is understood same may be varied in minor details not departing fromthe spirit of my invention as defined in the appended claims.

Iclaim: f J

1. A water power plant designed to be .located in deep current rivers and including spaced piers, bridges supported by the piers, boats adapted to rise and fall with the water and guided by the piers, hoisting bases resting upon the said boats, a fin wheel carried by the hoisting bases,-means.for transmitting power from the fin wheel to mechanism opened to permit pumping air which may a on the bridges, and mechanism connecting the hoisting bases with the bridges for. raising and lowering the latter, the boats being movable downwardly independently of the hoisting bases with the fall of the water to avoid straining the said mechanism.

2. A water power plant designed to be located in deep current rivers and including spaced piers, bridges spanning the tops of the piers, fiat boats guided by the piers and adapted to be submerged or raised, hoisting bases resting upon the fiat boats, a fin wheel carried by the hoisting bases and mechanism connecting the hoisting bases with the bridges for raising and lowering the same, the boats being movable downwardly with the fall of the water independently of the hoisting bases to avoid straining the said mechanism. l

3. A water power plant including spaced piers, boats located between the piers and movable upwardly and downwardly be tween the same, hoisting bases resting upon the said boats, a fin wheel carried by the.

hoisting bases, gearing connected with the fin wheel, worm hoisting screws vertically mounted between the piers and secured to the hoisting bases, the boats being movable downwardly independently of the hoisting bases to permit the boats to fall with the water without straining the said gearing, gears, and gear shifting blocks for connecting. the worm hoisting screws with the said gearing for raising and lowering the hoisting bases by the power from the fin wheel. I

4. A water power plant including piers spaced apart to provide a fin wheel passage and boat receiving spaces, bridges spanning the piers, boats guided between the piers in the said boat receiving spaces, a fin wheel operating in the fin wheel passage and car fall of the Water independently of the fin .Wheel to avoid straining the said mechanisni connected with the fin Wheel.

-5.'A Water power 7 plant embodying spaced piers, boatsguided between the piers,

afin wheel carried by the fiatboats; means foiitrans'mitting power from the fin Wheel,

araft located in advance of the fin Wheel and mounted to rise and fallwith the Water and pro'i rided with a screen for shieldingthe finwh'eel from floating objects',-the' .b'oats being movable downwaitdly independently of the fin wheel to fall With the Water Without straining the fin Wheel and the 'ineans for transmitting powertherefiol'n.

6; A Water power plant including spaced piers, an oyei he'adstructure connecting the fin wheeh boats guided by the piers, hoist-' ing bases resting upon the boats; aifin Wheel carried by the hoisting bases, gearing con- .necting the fin Wheel with the overhead "the fall of the \VEl-EGF independently of the hoisting bases to pievent training the gear- 111;; and the hoisting mechanism.

In testimony whereof I afiix my signature.
